FM4 Filter Stomp Box Modeler

The Line 6 FM4 Filter Pedal. Powerful, tone-bending filters and classic synth effects all in one box.

The Line 6 FM4 delivers accurate models of 16 new and vintage effects including Mu-Tron III, Moog, Arp, Korg, and Roland synths; Oberheim VCF; formant filter; and more. 4 user programmable channels. Simple to use and tough as nails. Has true bypass switching. From the gentle auto-wah of an envelope filter to the complete wackiness of mutated VCO controlled ring modulators, FM4 can get as strange as you want it to be.

The main features of the Line 6 FM4 include:

4 completely programmable presets available at the tap of a toe. No more need for multiple pedals for multiple effects
